Both stands are adjustable from 23.5 inches up to 42 inches high at the top of the shade. The diffuser shade is 15 inches across. See complete description at above Amazon link. Both have adjustment knobs at the tops of the bottom tripods, for height, and for the pitch of the diffuser shades. Bought for Covid-era video conferencing and online instruction -- rarely used. Cash only. Will do the handoff in the parking lot of the Houston Police Department Gessner Substation.
